Necromancer would have been my first choice, but... I don't think strength, speed, magic, or undead minions can withstand a firearm.
It would if you had a million zombies standing in front of you.
I would be somebody like Sephiroth (Final Fantasy VII) Destroy the planet and release enough Lifestream energy to turn into a God. That guy is a genius!
